Why did a pain management doctor refuse to accept me as a patient?

I moved to Kansas from Arizona in March 1, 2011. When I lived in Arizona, I was on pain management for two years. It took the doctor's office up until just this month (June) to fax my medical records to the doctor here in Kansas. I have to pay cash right now, because I don't have medical insurance yet, and this was the only pain management doctor that accepted cash payments. I called them for an appointment, and the girl in the office said there was a note on my file that said the doctor here in Kansas won't accept me as a patient. I asked why?, and she said there was no reason given. I replied, "there has to be a reason", and she suggested I call the doctor in Arizona to ask why. The doctor in Arizona said there was no reason on their account why I wouldn't have been accepted. The doctor in Arizona has been refilling a prescription for Hydrocodone since I've been in Kansas, but I don't know if they will continue doing that, since I'm not even living there anymore. I thought that was pretty decent of them to do that anyway. So my main concern is, how am I going to find a pain management doctor? I need my pain medicine, I have several major problems in my spine, and leg pain caused from the nerves in my spine. I'm at a loss to know what to do now. I also live in a very small town, 50 miles from Wichita. I called all the pain management doctors in Wichita, and none of them will accept cash either. I'm not familiar with the laws in this state, but I think we made a mistake moving here.
